So, it's as it sounds--both of my thumbnails have dents in them in roughly the same spot. I read this could be something called "Beau's lines," which can indicate "serious disease" (!!!) but I wasn't sure if they had to be on every finger. These are simply on my thumbnails.

I'll be honest, I haven't done so hot lately. My anxiety has been kind of high...I'm still worried about lymphoma due to some ache/soreness I've had off and on in my lower back/upper abdomen for...months and months now (since the summer).

I have dents in my thumbnails too but don't even want to know what disease you're referring to lol. Jeez, google really is a nightmare if even a fingernail can bring up the cause of a serious illness. Definitely not being rude here, I've been struggling with googling too and I think this proves how crazy some of those search results are.
